The energy tower is a device for producing electrical power. The brainchild of Dr. Phillip Carlson,[1] expanded by Professor Dan Zaslavsky from the Technion.[2] Energy towers spray water on hot air at the top of the tower, making the cooled air fall through the tower and drive a turbine at the tower's bottom.
